Numerical renormalization-group study of the correlation functions of the antiferromagnetic spin 1/2 Heisenberg chain
Hallberg, Karen A.; Horsch, Peter; Martinez Pino, Gerardo Guido (1995) [Artigo de periódico]We use the density-matrix renormalization-group technique developed by White to calculate the spin correlation functions (S2n+I S2n)=(-1) 1 w(l,N) for isotropic Heisenberg rings up to N=70 sites. The correlation functions ...
